TRlPLE THERMlC lVlOTOR.

SPECIFICATION forming part of Letters Patent Nol 313,181, dated March 3,1885. Application filed August 19, 1884. (N model.)

To all whom it may concern.-

Be it known that 1, WILLIAM S. OoLwnLL, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Triple Thermic Motors; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of referonce marked thereon.

Myinvention consists in the methods hereinafter described and specifically claimed, whereby a motor is generated by the induction of liquid bisulphide of carbon into a vapor-generator, and circulating it therein, said generator being contained within a steamboiler, and subjecting said liquid to heat contained within said steam-boiler to evolve vapor, and also superheating and expanding said vapor in a chamber or reservoir contained in said steam-boiler,thereby increasing its tension and maintaining the heat and expansion of said vapor until it has performed its office on the piston of the engine,and also automatically controlling the induction of said liquid into said generator, and also automatically controlling the pressure of said vapor, and also conveying the vapor exhausted irom the en gine by gravity to the condenser, and also returning the liquid bisulphide of carbon "to said generator heated to about its boilingpoint.

To enable others skilled in the art with which my invention is most nearly connected to make and use my invention, 1 will proceed to describe its construction and operation.

In the accompanying drawings, which form part of this specification, Figure l is a vertical section of an apparatus for carrying out the several methods stated and hereinafter more fully described. Fig. 2 is a horizontal section of the steam-boiler representinga plan of the bisulphide-of-carbon-vapor generator and expanding-chamber contained within said steam-boiler. Fig. 3 is an enlarged view of the regulating-valves for controlling the flow of theliquid bisulphide of carbon to the pump. (Shown in side elevation.)

Reference being had to the accompanying 5o drawings, A represents an ordinary furnace for the tubular steam-boiler B, which is also of ordinary construction, and furnished with the usual appendages of such boilers. Above the tubes 0 is arranged,within the boiler B, a generator, D, which increases in diameter 5 5 from the rear end of the boiler toward the front end, running zigzag, as shown in Fig. 2, and at its largest diameter communicates with avapor superheating and expanding chamber,

E, having conduit F, for conducting the vapor to the cylinder G of the engine, having a casing around it, which communicates with the casing H around the conduit F, supplied with steam from the boiler. This incasing of the cylinder G and conduitF is clearly and fully described and shown in Letters Patent No. 219,622, granted to me September 16, 1879, in which patent is also described and shown a steam-boiler having within it a generator for evolving liquid bisulphide of carbon into a vapor for a motor. The conduit F is provided with a valve, I, and safety-valve J, to which is attacheda pipe,

K, which communicates with the condenser L,which communicates with a vacuum-pump,

M. Substantially this arrangement of safety- 7 5 valve, condenser, and a vacuum-producing mechanism and the purpose and operation of the same are also described and shown in said cited patent. The throttle-valve N and lubricating device O,connected to and communi- So eating with the cylinder G, are also described and shown in said cited patent, and in Letters Patent No. 266,952, granted to me October 31, 1882. The generatorD is arranged on a horizontal plane, but part of it may be arranged at an angle to said plane, as indicated by dotted lines. (Shownin Fig. 1.) The rear end of the generator D communicates with a pipe, P, which enters and is arranged in a heater, R, and communicates with a pump, Q. This arrangement of pipe P, heater R, and pump Q, and the purpose and operation of said parts are fullyand clearly described in cited Letters Patent N 0. 266,952. The lower end of the heater R communicates with the. 93 exhaust of the cylinder G through the medium of pipe T, and its upper end communicates with a pipe, U, which communicates with the pipe K, which communicates with the condenser L, which communicates by pipe W with the vacuum-pump M,which communicates by pipe X with a washer, V. The condenser L also communicates with a well, Y, which] carbon is heated by the exhaust-vapor from communicates by pipe at with abalance-valve, the engine to about the boiling-point in its E, which by pipe 0 communicates with the pump Q. The balance-valve E is opened and closed'by the regulating-valve A, having chambers B G, diaphragm D, plunger F, lever G, and weight H, said valve communicating with the conduit F by means of a pipe, I), which is charged with water to about the dotted line 0.

The Vacuum-pump,washer, condenser, well, pump Q, balance-valve, and regulating-valve are all substantially shown, described, and

claimed, and their operation and purpose fully set forth in my application filed August 21, 1884, No. 141,109, which is a division-of my application for Letters Patent filed July 26, 1884, Serial No. 138.819, and are therefore herein desclaimed and need not be further described in this specification. The casing surrounding the cylinder G communicates with a steam trap,f, through the medium ofa pipe, g, and said trap communicates with the pump h by means of pipe 2', and said pump it communicating with the steam-boilerB by means of pipe '6. The packing mechanism for the valve-rod and piston of the cylinder communicate s with the well Y by means of the pipe is k, as described in said cited application. The water in the boiler B may cover or partially cover the generator D, or the water may be below the said generator, and the chamber E will be surrounded with steam.

The construction of the apparatus shown in the accompanying drawings and hereinbefore described will readily be understood from the foregoing description and by reference to the said cited patents and application. I will therefore proceed to describe the operation, which is as follows: The boiler B being tilled to the desired pointwith water, and the generator D charged with a sufficient quantity of liquid bisulphide of carbon for evolving vapor enough for starting the engine, and the well Y charged with the desired quantity of the liquid bisulphide of carbon, fire is then started in the furnace A,which heats the wami in the boiler B and evolves steam therefrom,which heated water or steam acts on the walls of the generator D and the steam sur rounds the superheating and expanding chamber E, so that theliquid bisulphide of carbon is evolved into a vapor and gradually expands from the rear end of said generator toward the superheating and expanding chamber, and is furthersuperheated and expanded in said chamber, whereby its tension is ininto the well Y, and from it through valve E to pump Q,which forces it through pipe P in the heater It, where the liquid bisulphide of passage to the generatorD, through which it circulates and is evolved into a vapor which is gradually increased in volume toward the superheating or expansion chamber E, in which it is further superheated or expanded, and, passing from said chamber, enters the conduit F and passes to the cylinder G, where, performing its office, it is exhausted into pipe T and makes the circuit, as before described.

The casing H and easing around the cylinder receive steam from the boiler B through the medium of the pipe Z, thereby maintaining the tension and expansion of the vapor until it has performed its office on the piston of the engine. In case the pressure of the vapor in the chamber E should be greater than determined upon, it will through the pipe I) act against the water in the said pipe, which, acting' against the diaphragm D and it against the plunger F, will move the lever G, which will force down the stem at and thereby close down the balance-valve E in accordance with the overpressure of the vapor. thereby correspondingly cutting off the supply of the liquid bisulphide of carbon from the pump Q and generator D until the pressure of vapor in the chamber E has decreased to that pressure fixed upon by the operator. The weight H will then open the balancevalve E and allow the desired quantity of liquid to flow to the pump Q and generator D.

The hot water produced by the condensation of steam in the casing of the cylinder G and easing H of the conduit F will flow into the trap f through thepipe g, and from said trap to the pump h, which forces itthrough the pipe i into the boiler B at about the boiling-point.

The 'condensable and incondensable gases which are by the vacuumpump drawn through the pipe WV are forced through pipe X into water in the washer V, as and forthe purpote described in said cited application.

The safety-valve J, which by pipe K communicates with the condenser L, is for the purpose of allowing the surplus vapor, in case of overpressure, to escape to the condenser L. The pressure of steam in the boiler B and the pressure of vapor in the chamber E are shown by gages a.

The means for carrying out my invention herein described are claimed in my application No. 152,712, filed January 13,1885,which is a division of this application required by the Office.
